[0031] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In the related technology, a stator and a mover can be arranged on a magnetic drive transmission line. By energizing the armature winding in the stator, the armature winding and the mover are magnetically coupled to drive the mover to move relative to the stator. When the stator is working, the circuits, cables and armature windings inside the stator will be energized, so the circuits, cables and armature windings will generate a lot of heat inside the stator. Excessive heat is not conducive to the long-term use of the stator.

[0033] Regarding the above situation, first of all, please refer to Figure 1-Figure 3 The present application proposes a stator 1 , which includes a main body 10 , an armature winding 20 and a fan assembly 30 .

[0034] The main body 10 has a accommodating cavity 11, a first air outlet 12 and a second air outlet 13, and the first air outlet 12 and the second air outlet 13 are both connected to the accommodating cavity 11; the armature winding 20 is connected to the main body 10, and the armature winding 20 will generate heat during the process of powering on and working. The armature winding 20 and the first air outlet 12 are both located on the same side of the main body 10, or it can be said that the armature winding 20 and the first air outlet 12 are arranged adjacent to each other, so that the airflow discharged from the first air outlet 12 can play a role in cooling the armature winding 20.

[0035] like Figure 2 and Figure 4As shown, the fan assembly 30 includes a first fan 31 and a second fan 32, and the first fan 31 and the second fan 32 are respectively arranged on two adjacent side surfaces of the main body 10, and the opening of the first fan 31 and the opening of the second fan 32 are both connected to the accommodating cavity 11. The first fan 31 and the second fan 32 can both generate airflow in the accommodating cavity 11, and the airflow in the accommodating cavity 11 can be discharged from the first air outlet 12 or the second air outlet 13, thereby playing a heat dissipation role for the main body 10 and the armature winding 20. The first fan 31 is arranged opposite to the armature winding 20, and the armature winding 20 is arranged adjacent to the first air outlet 12, so most of the airflow generated by the first fan 31 can be blown directly to the armature winding 20, and discharged from the accommodating cavity 11 from the first air outlet 12 to accelerate the heat dissipation of the armature winding 20; the second fan 32 and the second air outlet 13 are respectively located on two opposite sides of the main body 10, or it can be said that the second fan 32 and the second air outlet 13 are arranged opposite to each other, so most of the airflow generated by the second fan 32 will be blown directly to the second air outlet 13, increasing the air flow in the accommodating cavity 11, thereby improving the heat dissipation efficiency of the main body 10.

[0036] It should be noted that, in the embodiment of the present application, the first fan 31 and the second fan 32 are arranged on the main body 10, so that both the first fan 31 and the second fan 32 can generate airflow in the accommodating chamber 11, thereby increasing the air flow in the accommodating chamber 11 to accelerate the heat dissipation speed inside the main body 10. The first fan 31 directly blows the armature winding 20, which can directly dissipate heat for the armature winding 20 on the one hand, and the airflow blown by the first fan 31 will also be discharged from the first air outlet 12, increasing the air flow rate on the outer surface of the armature winding 20, so that the outer surface of the armature winding 20 can exchange heat with more cold air, thereby further playing a role in heat dissipation for the armature winding 20; at the same time, the second fan 32 also generates airflow in the accommodating chamber 11, further increasing the air flow in the accommodating chamber 11, thereby playing a role in auxiliary heat dissipation for the main body 10, so that the present embodiment can not only improve the heat dissipation efficiency of the armature winding 20, but also improve the heat dissipation efficiency in the main body 10.

[0037] It is understandable that if Figure 2 As shown, the armature winding 20 has a first end 21 and a second end 22 which are arranged opposite to each other. The first end 21 of the armature winding 20 is connected to the main body 10, and the first end 21 is located in the accommodating cavity 11. The second end 22 of the armature winding 20 extends toward the outside of the accommodating cavity 11. An air guide inclined toward the armature winding 20 can be provided at the second air outlet 13. The air guide can guide the airflow discharged from the second air outlet 13 to blow directly toward the second end 22 of the armature winding 20, so that the airflow discharged from the second air outlet 13 is directly blown onto the surface of the armature winding 20 outside the accommodating cavity 11, so as to improve the heat dissipation efficiency of the armature winding 20.

[0038] Exemplarily, a plurality of first fans 31 are provided, and the plurality of first fans 31 are arranged in parallel, and the plurality of first fans 31 are arranged opposite to the armature winding 20, thereby increasing the airflow volume blown by the first fan 31 to the armature winding 20 and improving the heat dissipation speed of the armature winding 20. Of course, a plurality of second fans 32 may also be provided to enhance the heat dissipation inside the main body 10. Among them, the first fan 31 may be any one of an axial flow fan and a centrifugal fan, and the second fan 32 may be the same type as the first fan 31 or may be different, and no specific limitation is made here.

[0039] See also Figure 3 In some embodiments of the present application, a plurality of first air vents 12 are provided, and the plurality of first air vents 12 are distributed on the upper and lower sides of the armature winding 20, so that the first air vents 12 can simultaneously dissipate heat for the upper and lower surfaces outside the armature winding 20, thereby improving the heat dissipation efficiency of the armature winding 20. Similarly, a plurality of second air vents 13 can also be provided to improve the heat dissipation efficiency inside the main body 10.

[0040] For further information, see Figure 2-Figure 5 In some embodiments of the present application, the main body 10 includes a connecting portion 14 and a base 15, and the first fan 31 is connected to both the base 15 and the connecting portion 14, thereby improving the installation and working stability of the first fan 31, and the armature winding 20 is arranged between the base 15 and the connecting portion 14, and a first air outlet 12 located on the upper surface of the armature winding 20 is formed between the armature winding 20 and the connecting portion 14, and a first air outlet 12 located on the lower surface of the armature winding 20 is formed between the armature winding 20 and the base 15. It can be understood that when the airflow is discharged from the first air outlet 12 at this time, the airflow will flow along the surface of the armature winding 20 from the inside of the accommodating cavity 11 to the outside of the accommodating cavity 11, thereby increasing the contact time between the airflow and the armature winding 20, thereby accelerating the heat dissipation of the armature winding 20.

[0041] Specifically, taking the armature winding 20 as a linear shape as an example, one first air vent 12 located on the upper surface of the armature winding 20 may be provided, extending along the length direction of the armature winding 20, and multiple first air vents 12 located on the lower surface of the armature winding 20 may be provided, and the multiple first air vents 12 are arranged at intervals along the length direction of the armature winding 20; or, there may be multiple first air vents 12 located on both the upper and lower surfaces of the armature winding 20, and the multiple first air vents 12 are arranged at intervals along the length direction of the armature winding 20. It is understandable that the armature winding 20 may be arc-shaped or other irregular shapes.

[0042] Among them, Figure 5As shown, the base 15 is connected to the connecting portion 14 and encloses the accommodating cavity 11, the base 15 has a mounting groove, the second fan 32 is arranged in the mounting groove, the base 15 provides a setting foundation and an installation space for the second fan 32, and the second air outlet 13 is arranged at the connecting portion 14, and the second fan 32 can be directly arranged opposite to the second air outlet 13.

[0043] See also Figure 1-Figure 2 In some embodiments of the present application, the main body 10 further includes a connecting member 17, and the connecting member 17 is fixedly connected to the base 15 and the first fan 31, so that the installation of the first fan 31 is more stable.

[0044] like Figure 5 As shown, the connecting member 17 has a guide surface 171, and the guide surface 171 is set at an angle with the connecting portion 14, that is, the guide surface 171 is set obliquely relative to the connecting portion 14. Specifically, the connecting member 17 is a hollow structure, and the opening of the first fan 31 is connected to the accommodating chamber 11 of the main body 10 via the cavity inside the connecting member 17. The larger the opening of the first fan 31, the more air is sucked into the accommodating chamber 11 by the first fan 31. Since the opening area of ​​the main body 10 and the connecting member 17 is fixed, the guide surface 171 is set obliquely, one end of the guide surface 171 is connected to the edge of the opening of the first fan 31, and the other end of the guide surface 171 is connected to the edge of the opening on the main body 10. The outside air can be sucked from the first fan 31 with a larger opening area, and then under the guidance of the guide surface 171, it passes through the cavity inside the connecting member 17 and finally enters the accommodating chamber 11 from the main body 10 with a smaller opening area, thereby increasing the flow rate of air in the accommodating chamber 11 and accelerating the heat dissipation inside the main body 10.

[0045] In which, the connecting member 17 can have multiple guide surfaces 171, each guide surface 171 is arranged corresponding to an opening of a first fan 31, and the number of guide surfaces 171 is the same as the number of first fans 31; or, the guide surface 31 is set to one and extends on the connecting member 17 along the length direction of the armature winding 20.

[0046] See also Figure 1-Figure 3In some embodiments of the present application, the first fan 31 has a first air inlet side 311 and a first air outlet side (not shown in the figure), the first air inlet side 311 is connected to the outside, the first air outlet side is connected to the accommodating chamber 11, and the first air outlet side is arranged opposite to the first air outlet 12, the first fan 31 drives the external air to flow through the first air inlet side 311, the first air outlet side, and the accommodating chamber 11 in sequence, that is, most of the airflow formed by the first fan 31 in the accommodating chamber 11 is blown toward the armature winding 20, and discharged from the first air outlet 12, and the first air outlet 12 is equivalent to the air outlet of the main body 10. Among them, the first fan 31 draws air from the outside to draw the external cold air into the accommodating chamber 11, and blows it toward the armature winding 20 to cool and dissipate the heat of the armature winding 20.

[0047] In some embodiments of the present application, the stator 1 further includes a circuit board (not shown in the figure), the circuit board is arranged in the accommodating cavity 11, and the circuit board is electrically connected to the armature winding 20. It can be understood that the stator 1 needs to be electrically connected to cables and optical fibers, the power supply supplies power to the armature winding 20 through the circuit board, and the optical fiber transmits information to the armature winding 20 through the circuit board. When the stator 1 is working, the circuit board generates heat in the accommodating cavity 11, and the fan assembly 30 can dissipate heat for the circuit board.

[0048] See also Figure 5 In some embodiments of the present application, the second fan 32 has a second air inlet side (not shown in the figure) and a second air outlet side 321, the second air inlet side is connected to the accommodating chamber 11, the second air outlet side 321 is connected to the outside, and the second air inlet side is connected to the second air outlet 13 (such as Figure 1 As shown in the figure, the second fan 32 drives the air in the accommodating chamber 11 to be discharged from the second air outlet side 321. It can be understood that the second fan 32 sucks out the air in the accommodating chamber 11 and discharges the hot air in the accommodating chamber 11 out of the accommodating chamber 11. At this time, the hot air in the accommodating chamber 11 is sucked away, and the air pressure in the accommodating chamber 11 is reduced, so that the external cold air is sucked in from the second air outlet 13, so that the air in the accommodating chamber 11 can be discharged from the second fan 32 with part of the heat, thereby accelerating the air flow rate in the accommodating chamber 11, thereby accelerating the heat dissipation speed inside the main body 10, so the second air outlet 13 is also equivalent to the air inlet of the main body 10.

[0049] Furthermore, the circuit board is located between the second air inlet side and the second air outlet 13. At this time, most of the cold air inhaled from the second air outlet 13 will first contact the circuit board and form heat exchange with the circuit board to cool down and dissipate heat for the circuit board. Then, the hot air in the accommodating chamber 11 will be sucked out by the second fan 32 and discharged outside the accommodating chamber 11.

[0050] In some embodiments of the present application, the main body 10 also has a first side surface, a second side surface and a third side surface (not shown in the figure) connected in sequence, the first side surface is provided with an armature winding 20 and a first air outlet 12, the second side surface is provided with a second fan 32 or a second air outlet 13, and the third side surface is provided with a first fan 31.

[0051] Among them, Figure 6 As shown, a slot 16 is provided on the third side, and the slot 16 is used for inserting an external cable. The cable may include electric wires and optical fibers, etc. The slot 16 may be used for inserting electric wires to supply power to the armature winding 20; the slot 16 may also be used for inserting optical fibers to transmit information to the stator 1.

[0052] It is understandable that the slot 16 is located on the third side and is arranged opposite to the armature winding 20, so that the cable can directly connect the slot 16 and the armature winding 20 in a straight line, so that the wiring in the stator 1 can be more convenient and neater, and the crossing, entanglement or bending of the cable in the stator 1 is reduced. The embodiment of the present application does not limit the shapes of the first side, the second side and the third side. Preferably, the third side is a plane, so that after the plug of the cable is inserted into the slot 16, the plug fits with the third side to prevent the cable plug from loosening or falling off.

[0053] In the second aspect, an embodiment of the present application also provides a magnetic drive conveyor line, including a base, a mover (not shown in the figure) and a stator 1 as described in any of the above embodiments, wherein the stator 1 is arranged on the base, and the mover is slidably connected to the stator 1.

[0054] Specifically, the base provides a setting foundation for the installation of the stator 1, and the mover slides on the stator 1 to achieve the purpose of transporting the workpiece. In the stator 1, the fan assembly 30 can work synchronously, and most of the airflow blown out by the first fan 31 is directly blown to the armature winding 20, and then discharged from the first air outlet 12 to increase the air flow rate on the outer surface of the armature winding 20, thereby dissipating the heat for the armature winding 20; the second fan 32 can suck out the hot air in the accommodating cavity 11 and discharge it from the accommodating cavity 11 to dissipate heat inside the main body 10, thereby reducing the accumulation of heat on the stator 1, which is beneficial to the long-term transportation work of the magnetic drive conveyor line.

[0055] In some embodiments of the present application, the base includes a slide rail, the mover includes a magnet array and a sliding member, the magnet array is slidably connected to the armature winding 20, and the sliding member is slidably connected to the slide rail.

[0056] It can be understood that the armature winding 20 in the stator 1 can extend in the horizontal direction, the extension direction of the magnet array is parallel to the extension direction of the armature winding 20, the stator 1 is arranged on the base, and the armature winding 20 drives the mover to slide by coupling with the magnet array. In order to ensure the stability of the mover, a sliding part that cooperates with the slide rail is provided on the mover, so that the mover is slidably connected to the base. The slide rail on the base can provide support and guidance for the mover and make the mover more stable during operation.

[0057] Among them, the embodiments of the present application do not limit the specific type of sliding parts. For example, the sliding part can be a slider with a ball. When the mover moves, it can drive the ball slider to roll on the slide rail. The sliding cooperation between the ball slider and the slide rail can be used to support the mover and reduce the load of the mover, and the cooperation between the ball slider and the slide rail can reduce friction. For another example, the sliding part can be a slider with a slide groove, and the slide groove is used to accommodate the slide rail. When the mover moves, it can drive the slider to move along the slide rail. The cooperation between the slide groove and the slide rail can limit the slider to prevent the mover from shifting with the slide rail during the sliding process. Or, the sliding part can be a roller, and a plurality of rollers are clamped on both sides of the slide rail to limit and guide the movement of the mover.

Therefore, the terms describing the positional relationships in the drawings are only used for illustrative purposes and cannot be understood as limitations on this application.
